So confused

So currently I am 8 days late and my last text was negative. This wouldn’t be my first pregnancy but I don’t recall waiting this long for a positive result. I woke up this morning to a very light pink discharge and sore Breast( like they are too painful to even touch). I don’t feel like wasting anymore money on test to get a negative but I really feel like maybe I ovulated late and I could be pregnant. Has anyone gotten a BFP a week or more after testing negative?
